ROTOR BLADE• New rotor blade design for shorter production times and improved transportation • Flatback profile optimised for production and transportation• Trailing edge serrations for minimum noise emission• Use of Impact Absorption Layer technology (IAL) for durable erosion protection

HUB• Separate main bearing unit for a more compact design• Optimised for maintenance thanks to easy hub access• Integration of electrical components protected in the hub

GENERATOR• Generator division for optimised logistics• Short production times thanks to use of pre-fabricated aluminium form-wound coils • Fully enclosed for optimum protection against external influences

MACHINE HOUSE• Compact design optimised for transportation

PERFORMANCE INCREASE WITHIN THE EP3 PLATFORMThe E-126 EP3 and the E-138 EP3 are two WECs for wind classes IIA and IIIA which have evolved from the EP3 plat-form. Thanks to a significant increase in output and efficiency, they provide a convincing overall performance in this high-volume segment. An annual yield of 14.28 million kWh is forecast for the E-126 EP3 (HH 135 m) at typi-cal wind class IIA locations (7.5 m/s). For the E-138 EP3 (HH 131 m) – a completely new type of WEC in the EP3 platform portfolio, which up until now did not include a low-wind con-verter – an annual yield of more than 13.2 million kWh is estimated at typi-cal wind class IIIA locations (7.0 m/s).
